Oo-types in collection. 



The difference in size between the sexes in this species and in 

 M. antilopinus has probably been much overrated, owing to the fact 

 that in each case the typical male specimen figured by Gould is very 

 old, the last molar having been up and in use for some time ; 

 whereas the female is immature or barely adult, and aU recent 

 writers have merely copied Gould's statements on the subject. 

 There is undoubtedly a difference in size, but it is probably little 

 more than occurs in the other large Kangaroos. 



I cannot distinguish specifically the Kangaroo described as M. eru- 

 lescens, which seems to be merely a more rufous form of the present 

 species. As to colour, every intermediate gradation appears to 

 occur, and the skulls of the two forms are quite identical. In a 

 general way South-Australian specimens belong to " erubescens " 

 and New-South-Wales ones to robusius, but specimens agreeing with 

 both are often found in one and the same place.

* When in the tables of measurements specimens are said to be " stuffed " 

 which are afterwards put down as " skins " in the lists of specimens, it means 

 that after the dimensions given were taken the animal was unstuffed and' made 

 into a skin.
